Is the line a good fit for the data in the scatterplot?

• There are an equal number of data points above and below the line, so the line is a good fit.

• There are an equal number of data points above and below the line, but the line does not follow the trend, so it is not a good fit.

• There is no relationship between x and y, so the line is not a good fit.

• There is a non-linear association between the x and y values, so the line is not a good fit.

• Positive Association
• Negative Association
• No Association
• Non-Linear Association
